An alleged statement by General Alphonse Juin before the battle said: "For fifty hours you will be the absolute masters of what you will find beyond the enemy. Nobody will punish you for what you will do, nobody will ask you about what you will get up to."[2] Recent research has showed this statement was forged after the war by Italian victims' associations and is linked to the perception of the crimes by the Italians rather than an official policy of the French Army.[3]

Monte Cassino was captured by the Allies on May 18, 1944. The next night, thousands of Goumiers and other colonial troops scoured the slopes of the hills surrounding the town and the villages of Ciociaria (in South Latium). Italian victims' associations such as Associazione Nazionale Vittime delle Marocchinate alleged that 60,000 women, ranging in age from 11 to 86, suffered from violence, when village after village came under control of the Goumiers. Estimates made by the Italian Ministry of Defence in 1997 set the figure at 2,000 to 3,000 female victims.[4] The number of men killed has been estimated at 800.[5] In fact, due to incomplete reports of the crimes, a precise account is impossible.[6]

The mayor of Esperia, a comune in the Province of Frosinone, reported that in his town, 700 women out of 2,500 inhabitants were raped, resulting in many deaths. According to Italian victims associations, a total of more than 7,000 civilians, including children, were raped by Goumiers.[7]

It praises the fighting ability in difficult terrain and "Unfortunately for the Goumiers, their military success did not prevent their fearsome reputation from taking its toll as exceptional numbers of Moroccans were executed—many without trial—for allegedly murdering, raping, and pillaging their way across the Italian countryside."
